Synonyms: polymer polyethylene, High-density Polyethylene, high-density Polyethylene, PEHD.Chemical structural formula: At present, the polymer polyethylene gas engine that undergoes the additives, which make be a polymer under pressure of varying sizes allow a polymer with size ranging from low molecular weight (oil or concentrated manner) to the high molecule size (looks solid, flexible).Physical properties: HDPE has a chemical structure that is branched branch (branching), less so with the attraction between molecules of the polymer is relatively high. There is strength. When high density, hardness and ductility increased, but when the density decreased skin cracked its easy to heat, not much but resistant to chemicals by thermal resistant (up to 110° C temperature resistant and withstands temperatures up to 120° C in a short range) but not resistant, high-temperature steam cooker (Autoclave) plastics PP (Polypropylene, symbol, number 5) and chemical resistance than LDPE (Low-density polyethylene, symbol, number 4) to withstand the weather well enough, but the air permeability. HDPE opaque white, transparent There is a slip it in the toughness and flexibility. There is no odor. No flavor. There is a density lower than water so it floats in water. Can mix different color.History: Ethylene polymer (Polyethylene or Polythene) was discovered in 1933 by Reginald Gibson and Eric Fawcett haengborisat Imperial Chemical Industries (ICI) in England. This type of material is LDPE and HDPE 2 format by using the material and film production LDPE for packing. HDPE stronger than section. Use, manufacture, packaging, water pipes and automotive devices. HDPE is a Thermoplastic Polyethylene materials (Thermoplastic plastic that can be recycled is melting.) derived from the petroleum industry. Align the plastic that has been a symbol number 2, which means the Resin Identification Code 2 for the classification of the type of plastic in the merge new (recycled) In 1945, Earl Tupper haengborisat note that DuPont ® polymer ethylene polymer with toughness. Durable, can be cast in printed form, with the size, shape and color combination, there are various colors, it started with the production of glass and plastic bowl which is popular because it is light weight, colour and subsequently produced the container with lid by. Which is the source of food containers has been popular in those days, in the name of Thap poewae (Tupperware ®).Usage: HDPE chemical resistant and many types of solvents. Flexible impact shocks Not easy to crack Can be utilized in various tasks, especially the production of containers from a blow from the mould (blow molding), due to contraction in the mold. Does mold removal from the mold easier. Container made from HDPE bottle such as fresh milk, laundry detergent bottle. The oil tank in the automotive, plumbing, plastic bags, folding tables & chairs, etc, in addition to a padded floor HDPE pond landfill to prevent leakage of chemicals into the ground and natural sources. Examples of products that are made from HDPE.-Bottle of bottled drinking water filling ice tray.-Containers, jars, boxes, packaging, food, jars, medicine and vitamins.-Chemical dispenser, soap dispenser (pump bottles) bottles of laundry detergent talcum.-Crate packing boxes and bags-Child's play-Electrical insulation-Table and chairsSynonyms: polymer polyethylene, High-density Polyethylene, high-density Polyethylene, PEHD.Chemical structural formula: At present, the polymer polyethylene gas engine that undergoes the additives, which make be a polymer under pressure of varying sizes allow a polymer with size ranging from low molecular weight (oil or concentrated manner) to the high molecule size (looks solid, flexible).Physical properties: HDPE has a chemical structure that is branched branch (branching), less so with the attraction between molecules of the polymer is relatively high.
